This document introduces the TPS755xx family of 5A low dropout regulators, which includes four fixed voltage option regulators with integrated power-good (PG) and an adjustable voltage option regulator. These devices are capable of supplying 5A of output current with a dropout of 250mV (TPS75533). Therefore, the device is capable of performing a 3.3V to 2.5V conversion. At full load, quiescent current is 125µA and drops down to less than 1µA when the device is disabled. The TPS755xx is designed to have fast transient response for large load current changes.
The TPS755xx family includes four fixed-output voltage regulators (1.5 V, 1.8 V, 2.5 V, and 3.3 V) and an adjustable regulator (TPS75501). These devices are designed to supply up to 5 A of output current with a typical dropout voltage of 250 mV at full load for the TPS75533 model.
Key features include fast transient response, low quiescent current (typically 125 µA), and integrated power-good status indicators. The regulators are available in TO-220, TO-263, and surface-mount packages with thermal shutdown protection.
